for each $-1 < q < 1$, bozejko and speicher's q-gaussian functor is a natural and important generalization of voiculescu's free gaussian functor. we study a class of subalgebras of the corresponding q-gaussian von neumann subalgebras. we construct a riesz basis in the spirit of radulescu in the q-fock space. then we use this basis and follow popa's approach to show that when $|q| < 1/9$ , the generator subalgebras are maximal amenable inside those q-gaussian algebras. this is joint work with sandeepan parekh and koichi shimada.
